Big Thompson flows are dropping now as we drop the water level at Estes. The rate of drop in the release to the river is following the rate of drop in water elevation of the reservoir. They've got the gates on the dam under a maintenance test.
What that means is, the changes are not being made incrementally. They are just slowly declining. So, in all, we went down about 30 cfs today, November 18. The river flows below the dam dropped to 270 cfs and continue to decline. They'll keep dropping through next week and the following weekend. By Monday, November 28, we're anticipating we'll be back to more normal flows for this time of year which are around 20-25 cfs.
Let me know if you have any questions.
